A technique includes modeling assignments of a plurality of nodes to a plurality of shards associated with a database operation based on a target throughput for the plurality of nodes. The modeling includes constraining the assignments based on an aggregate outflow from the plurality of nodes. The technique includes initializing the aggregate outflow to be less than the target throughput; and determining the assignments based on the modeling.

Assigning nodes to shards based on a flow graph model

A technique includes applying a first mapping to associate a plurality of data records for a plurality of database nodes with a plurality of segments of a storage that is shared by the database nodes; and applying a many-to-many second mapping to associate the segments with the database nodes.
